Question

?cobalt has a density of 8.90 g. what volume would 17.8 g of Cobalt occupy?

Answer 1

Step-by-step explanation:

Given parameters:

Density of cobalt = 8.9gcm⁻³

Mass of cobalt = 17.8g

Solution

Density can be defined as the mass per unit volume of a substance:

Density =
`(mass in g)/(volume in cm^(3) )`

The unknown in the problem is Volume:

Volume =
`(mass)/(Density)`

Volume =
`(17.8)/(8.9)` = 2cm³
